` position, this recessed portion is adapted to be positioned in the outlet passage 16. This portion 34 of the valve stem has a substantially semi-annular recess on each side of the valve stem, the inner Walls of the ends of the semi-annular recesses projecting out-r ward to form pointed edges 27 and 28 0pposite one another as shown in cross-section in Fig. 4. These edges are on each side of the valve stem so that the valve stem may be reversed. -The reason for these edges obviously, is vso that the water may freely pass the valve stem with little impediment. But below the recessed portion 26 the valve stem is again of the larger diameter to it snugly into the opening of the En 17 to prevent water from the outlet passage to back into the inlet passage. Thev portion of the valve stem operating in the inlet passage 15 has an annular groove 29 to aii'ord the largest water passage possible. At the lower end of the valve stem is secured a washer of rubber or other suitable packing material to securely engage the valve seat 12. In the present instance, the lower end of the valve stem is cup-shaped to receive a washer 3Q..

This washer is held in place by means of a screw 31.

The operation of the ball cock is as follows: When the ball descends, its lever 25 will raise vthe valve stem to the position shown in Fig. 2. In this raised position the recessed portion 34 of the valve stem will be positioned in the passage 16, thus when the water rushes in throu h inlet passage 15v and around the upper en of the baffle 17, it will rush past the recessed portion 34, out through outlet passage 16. By means of the baiiie 21, the water will be deflected downlward and thus no water pressure will be i, exercised upward into chamber 22 and therefore no packing or the like is required. It will also be noted that the diameter of valve seat 12 is considerably less than the diameter'of the water passages 15 and 16, and therefore the water passing into apassage of larger diameter will shoot through with .considerable force thus to prohibit a stagnation of water in the outlet passage which might otherwise pile up and back into the chamber 15.

Within the valve casing and directly in the path of water passing through the outlet passage is a""projecting cup or delector 32 hollowed out to divert some of the passing water outward to a sidespout 33 which has al down turned end for'delivering the water thus diverted through the flushing valve of the water closet into the bowl where it replenishes the water seal after each flushing of the bowl.

While there, is herein shown and described only one embodiment of the invention it is to be understood that various changes and modifications may be made by those skilled in the art without departing from the scope of the invention as deined in the appending claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. In a ball cock, a casing having a cylindrical bore at its upper end, transverse battles in said casing forming a water channel having a reverse bend, said baffles having openings in alinement'with said bore, a valve at the lower end of said casing, said valve having a valve stem adapted to be introduced v and removed from said casing through said alined openings, the portion of said valve stem positioned in the water ehannel when the valve is open being recessed, said recessed portion terminating in edges at the diametrically opposite sides of the stem which when in position for operation will present an edge to the direction of flow so that the water will freely pass with little impediment.

2. In a ball cock, a casing having a cylindrical bore at its upper end, transverse baffles in said casing forming a water channel having a reverse bend, said baiiies havin@ openings in alinement with said bore, a va ve at the lower end of said casing, said valve having a valve stem adapted to be introduced and removed from said casing through said alined openings, one of said bales being positioned below the cylindrical bore which serves to deect the water from said bore thereby to dispense with packing at such place.

3. In apparatus of'the class described, a casing, a valve in saidcasing comprising a cylindrical stem having a cut away portion to provide a water passage, battles in said casing through whichsaid cylindrical stem is slidably mounted, all so constructed and arranged that the valve may be removed longitudinally from the casing as one piece.

4. In 'apparatus of the class'described, a casing having an inlet and an outlet, a goose-neck passage between the inlet'and the outlet, an extension on the casing in line with the inlet, a cylindrical valve stem slidably mounted 'in said extension and passing through said goose-neck passage, said valve stem having cut away portions to coperate with said goose-neckpassage, all for the purpose described.

5. In, apparatus of the class described, a

casing having ma mle', and am outl@ @ml TQ vers@ bend therein, :m extension im said cas= ing im line With 2th@ inlet, a cyindca aperfum communicating from said inlet t@ the end 0I" said extension, a cylindrical Valve stem sldably mounted im said aperture and having a cua away portion m'mmg m wat@ passage? subsamiay as described.,
